 species subdue other plants by their creeping roots, or bind them 

 by their runners). Lin. gen. no. 295. Juss. 141. Pervinca,

LIK. STST. Penttindria, Monogynia. Calyx 5-cleft ; seg- 

 ments linear or subulate, acute. Corolla salver-shaped ; tube 

 longer than the calyx ; throat bearded ; segments of the limb 

 flat, oblique, truncate at the apex. Stamens 5, inserted in the 

 throat, inclosed ; filaments short ; anthers ending each in a hairy 

 membrane at apex, which connive over the stigma ; stigma 

 bearded, seated on a flat orbicular disk, which is grooved round 

 the circumference. Glands 2, alternating with the ovaria ; gla- 

 brous as well as them. Follicles 2, erect, terete, narrow, dehis- 

 cing lengthwise, few-seeded. Albumen fleshy. Seeds cylin- 

 drical, naked. Creeping, suflruticose, or herbaceous plants. 

 Leaves smooth, shining, opposite. Flowers axillary, solitary,

1 V, MINOR (Lin. spec. 304.) stems procumbent ; leaves ellip- 

 tic-lanceolate, glabrous ; calycine segments linear-lanceolate, 

 bluntish ; segments of corolla broadish at top. I? . H. Na- 

 tive of Europe, as of Germany, Switzerland, France, Italy, 

 &c. In Britain it has been found in many places, in hedges 

 and woods, in rather damp situations. Smith, engl. bot. t. 917.

 Flowering stems usually erect. Flowers void of scent. Co- 

 rolla blue ; with white throat, varying to purple and white, of 

 a smaller size than those of V. major. This species varies 

 much in the colour of the flowers ; they are also sometimes 

 double : and the foliage is sometimes variegated, either with 

 white or yellow stripes.

2 V. MA'JOR (Lin. spec. p. 304.) stems erectish ; leaves 

 ovate, acute, ciliated ; calycine teeth linear-subulate, ciliated, 

 usually with a small tooth on each side at the base ; segments of 

 corolla broad, obovate. T? .H. Native of Europe, as of France, 

 Spain, Italy, Switzerland, &c. With us it is more common than 

 I", minor, in moist woods and hedges ; but these are probably 

 both escapes from gardens. Smith, engl. bot. t. 514. Curt,

 Corollas fine purplish blue. Flowering stems erect ; barren ones 

 creeping. There is a variety of this with variegated leaves.

 Hook, bot. mag. 2002.) stems 

 herbaceous, procumbent, root- 

 ing ; leaves oblong-lanceolate, 

 minutely ciliated on the edges 

 while young ; calycine segments 

 linear-subulate, acute, glabrous ; 

 segments of corolla lanceolate, 

 falcate. T.H. Native of Hun- 

 gary, in open, chalky, sandy 

 hills. Flowers purplish blue. 

 A most elegant plant when in 

 blossom.

Cuh. As these plants delight to grow under the cover of 

 trees and bushes, they may be made ornamental, if they are 

 planted in shrubberies, where they will spread and cover the 

 ground ; and as their leaves continue green all the year, they 

 will have a good effect in winter, and their elegant and delicate 

 flowers appearing a great part of summer will add to the variety. 

 They are easily increased by separating the rooted trailing 

 shoots. 



XXXVIII. CATHARA'NTHUS (from caflopoc, katkaros, 

 pure, and avBof, anthos, a flower ; in reference to the neatness 

 and beauty of the flowers). Vinca species, Lin.

 over the stigma. Anthers mucronate, not membranous at top, 

 sessile. Stigma capitate, marginate, bearded at top, and fur- 

 nished with a cup-shaped membrane below, which sheaths the 

 upper pan of the style. Hypogynous glands 2, elongated like 

 the ovaria. Follicles twin, small, terete, glabrous, 2-celled, 

 dehiscing inside ; dissepiment double, taking its rise from the 

 suture, which is plaited inwards. Seeds 16-20 in each follicle,

 ovate-acuminated above, grooved and rugged from sharp tuber- 

 cles on one side, and smooth on the other side. Albumen fleshy.
